ObjectiveTo analyze the status of DACH1 gene promoter methylation and explore its association with the expression of DACH1 gene promoter methylation and clinical significance of endometrium carcinoma(EC).Methods From February 2004 to August 2008,a total of 80 EC tissue samples with comprehensive surgical pathology staging were collected and used for this study.Twenty normal endometrium tissues in 2008 were abtained from the fractional curettage because of dysfunctional uterine bleeding as control.All samples were confirmed pathologically.Methylation specific PCR (MSP) was performed to detect the promoter methylation of DACH1 gene,and analyze its influence on the expression of DACH1 and the relationship between DACH1 promoter methylation and clinicopathological factors in EC.DACH1 protein expression was detected by western blot.Chi-square test and Pearson test were used for statistical analysis.ResultsThe rate of promoter methylation of DACH1 gene in the EC tissues was significantly higher than that in the normal endometrium issues (30％ vs.5％,P ＜ 0.05).There was an association between the expression of DACH1 and DACH1 gene promoter methylation ( r =- 0.30,P ＜ 0.01 ).There was statistical difference between the methylation of DACH1 and the pathological grade ( P ＜ 0.05 ) or histological type ( P ＜0.05).But DACH1 gene methylation was not related with the age,stage,myometrial invasion depth and lymphnode metastasis (P ＞ 0.05 ).Conclusions DACH1gene promoter methylaion could lead to a decrease or absence in the DACH1 expression in EC.The promoter methylation of DACH1 gene may induce the inhibition of DACH1 expression,which might be one of the mechanisms of DACH1 gene inactivation in human EC.

OBJECTIVETo investigate the efficacy of allogeneic peripheral blood stem cell transplantation (PBSCT) in the treatment of severe aplastic anemia (SAA) and severe infection.

METHODSA patient with SAA and pseudomonas aeruginosa septicemia was treated with PBSCT from an HLA-identical sibling with cyclophosphamide (CY) and total body irradiation (TBI) for conditioning. The patient was infused with 20.3 x 10(8)/kg mononuclear cells including 61.0 x 10(6)/kg CD34(+) cells following the conditioning regimen.

RESULTSTwelve days after PBSCT, the absolute neutrophil count (ANC) of 1.0 x 10(9)/L was achieved, with platelet count > 50 x 10(9)/L at twenty days. The donor origin of engraftment was confirmed by polymerase chain reaction (PCR) analysis of short tandem repeats at the end of the first, sixth and twelfth month. The patient's body temperature dropped to normal level when her ANC reached 0.5 x 10(9)/L on day 10, and the bacterial culture of blood sample became negative subsequently. Symptoms and signs of acute or chronic graft versus host disease (GVHD) were not observed in 30 months after PBSCT.

CONCLUSIONSHematopoiesis was reconstituted shortly after PBSCT. The combination of CY and TBI and the infusion of sufficient peripheral blood stem cells may contribute to the successful engraftment. PBSCT may be considered as the first choice when hematopoietic stem cell transplantation is needed for SAA patients complicated with severe infection.

Objective:To explore the relationship between knowledge of a friend's non-suicidal self-injury (NSSI) behavior and self injury and suicide behaviors of adolescents.Methods:From January 2020 to January 2021, totally 1 683 students from a middle school in Xiamen were randomly selected by cluster sampling.The suicide items of the self-injurious thoughts and behaviors interview(SITBT) were used to assess whether students were aware of their friends' self injurious history and their self injurious behaviors.The suicide items of the mini international neuropsychiatric interview for children and adolescents (MINI-KID) were used to assess students' suicide ideation and behavior.The data were statistically analyzed by SPSS 21.0 software.Logistic regression model was used to analyze the relationship between knowledge of a friend's NSSI and adolescents' own self-reported NSSI and suicidal behaviors.Results:A total of 1 683 junior and senior high school students completed the survey, including 412 (24.4%) who knew their friend's NSSI history and 1 271 (75.6%) who did not know their friend's NSSI history.There were statistically significant differences between the adolescents known and unknown friends' NSSI histories in terms of age, gender, whether they were left-behind children, mental disorders, their own NSSI, suicide attempts, and suicidal ideation (all P<0.05). Knowledge of a friend's NSSI behavior had positive predictive effect on adolescents' own NSSI behavior ( β=0.558, OR=2.01, 95% CI=1.58-3.88), suicidal ideation( β=0.238, OR=3.03, 95% CI=2.08-5.55), and suicide attempts ( β=0.233, OR=2.88, 95% CI=1.55-5.45) (all P<0.05). Conclusion:Knowledge of a friend's NSSI behavior may have an impact on adolescents' own self-injury and suicidal behavior.

Objective To investigate the expression levels of serum miR-210and miR-375in patients with non-small cell lung cancer (NSCLC).Methods A total of 25NSCLC patients (NSCLC group) and 14healthy volunteers (control group) were enrolled in this study.The relative expression levels of 9miRNAs (miR-182, miR-126, miR-31, miR-21, miR-221, miR-200b, miR-183, miR-210and miR-375) in 6 NSCLC patients and 6healthy volunteers were measured by RT-qPCR.The dysregulated miRNAs will be selected as candidate miR-NAs.The diagnostic value were evaluated by ROC curve.Results Compared with control group, 2 (miR-210and miR-375) out of 9miRNAs were up-regulated in NSCLC group, and the differences were statistically significant (P＜0.05), while the other 7miRNAs were not consistent with the reported literatures.Therefore, miR-210and miR-375were selected as candidate miRNAs.We found that the relative expression level of miR-210in the lung adenocarcinoma group was significantly different from control group (P＜0.05), while there was no significant difference between the squamous cell carcinoma group and the control group (P＞0.05).There was no significantly statistical difference in the relative expression level of miR-375between lung squamous cell carcinoma group, lung adenocarcinoma group and the control group (P＞0.05).The AUC of serum miR-210of lung adenocarcinoma group was 0.737 5 (95％CI:0.498 3-0.976 7, P=0.091 4) with a medium diagnostic value.Conclusion MiR-210is highly expressed in the serum of patients with lung adenocarcinoma, suggesting that miR-210may be a novel tumor marker for the diagnosis of lung adenocarcinoma.The value of miR-375in the diagnosis of lung cancer still needs to be further explored.
